dhcpcd-discuss

Hi,

I'm calling dhcpcd with the -S option to configure
static ip's but I noticed that the configured netmask
is not (always) honored:

# dhcpcd -d -S ip_address=172.1.2.3/21 br0:gdm
dhcpcd-6.11.0 starting

I asked for a netmask with /21 bits but got only /16.
The same happens with:

# dhcpcd -d -S subnet_mask=255.255.248.0 -S ip_address=172.1.2.3 
br0:gdm


I suppose that this is the intended behavior and that there
is a valid explanation for this, nevertheless is there a way
to force the program to do exactly what it's told ?

thanks,

giorgio
